Methodology
  • Specimen UMMP VP 115547 (L1 vertebra) was scanned with a Nikon XT H 225ST μCT system housed in the Department of Earth and Environmental Sciences at the University of Michigan. Scans were collected with the following settings: energy settings, 160kV, 132uA; source to object distance, 158.055408477783 mm; source to detector distance, 1105.0 mm; scanned with 1024 projections; voxel size, x = y = z = 0.0286073141779172 mm; slice dimension (in pixels), x = 1519, y = 1522; number of slices, 1395 16-bit TIFF images. Original floating point grey values were scaled to span the unsigned 16-bit integer range using an offset of +260.823 and a scale factor of 41.192. Additional metadata can be found in the xtekct and ctprofile.xml files.
Description
  • Reconstructed CT slices for a first lumbar vertebra of Sifrhippus grangeri (University of Michigan Museum of Paleontology catalog number UMMP VP 115547) as a series of TIFF images. Raw projections are not included in this dataset. The reconstructed slice data from the scan are offered here as a series of unsigned 16-bit integer TIFF images. The upper left corner of the first image (*_0000.tif) is the XYZ origin. In some publications this species is referred to as Hyracotherium grangeri.

Methods:
Specimen UMMP VP 115547 (L1 vertebra) was scanned with a Nikon XT H 225ST μCT system housed in the Department of Earth and Environmental Sciences at the University of Michigan. Scans were collected with the following settings: energy settings, 160kV, 132uA; source to object distance, 158.055408477783 mm; source to detector distance, 1105.0 mm; scanned with 1024 projections; voxel size, x = y = z = 0.0286073141779172 mm; slice dimension (in pixels), x = 1519, y = 1522; number of slices, 1395 16-bit TIFF images. Original floating point grey values were scaled to span the unsigned 16-bit integer range using an offset of +260.823 and a scale factor of 41.192. Additional metadata can be found in the xtekct and ctprofile.xml files.

Format:
The reconstructed slice data from the scan are offered here as a series of unsigned 16-bit integer TIFF images. The upper left corner of the first image (*_0000.tif) is the XYZ origin. At the time of posting, this format can be loaded in a variety of viewers, such as 3D Slicer, Amira, Avizo, Dragonfly, ImageJ, and VG Studio. Projections are not included in this dataset.
